This updates `background-blend-mode`, `mix-blend-mode`, and `isolation`
to be animation type `discrete` rather than `none`. This reflects
169b0e1 but isn't reflected
on the published spec as the published spec is out of date - see
https://github.com/w3c/fxtf-drafts/issues/547
Gains us 26 WPT tests.
All remaining failing subtests in border-image-width-interpolation.html
are related to incorrect handling of mixed dimension and percentage
interpolation and are fixed by #6142.
This means that we now calculate the inner width correctly for `display:
inline-block` nodes when we have `box-sizing: border-box` and
`min-width`, as we would previously assume these dimensions were all `0`
Previously, the first `HTMLHtmlELement` in the given document would
always be used when determining whether to propagate background
properties to the body element. This meant the wrong root element was
used for SVG `foreignObject` elements, which could lead to a crash.
This also fixes a bug in the view transitions code that was
required to get the imported test to pass. The code for setting
the initial containing block size just did not set the right thing,
since doing so would trigger an error later on.
That later error resulted from walking up the tree, without
considering that the document element has a parent that is not
itself an element. (and then doing element things to it)
...when `LengthOrAutoOrCalculated` holds calculated value. We were
incorrectly assuming that if contained value is not auto, then it must
be a length.

Now follows the same pattern as PaintableBox and StackingContext, where
it exits if hidden, then hit tests children, then hit tests itself if
it's `visible_for_hit_testing()`.
This change removes premature reset of
`block_container_y_position_update_callback`. Also makes callback
private in `BlockMarginState`, because resetting it independently of
currently accumulated margins is incorrect.
Lots of test expectations are updated, but there is no visual
difference.

We also support interpolating from a CalculatedStyleValue to a
compatible dimension or percentage style value.
This also brings with it a couple of improvements in how we handle
interpolation between mixed dimension and percentage types in terms of:
- Proper simplification of the resulting calc()
- Improved handling of interpolation outside the 0-1 range
This behaviour should only apply to literal percentages as clarified
here: 4ee8429
We were also doing this wrong by converting the numeric type of the calc
to Length which was causing values to be defaulted to 1 instead (hence
the new passing tests for computed values as well)
This ensures that we clamp values for properties like padding-* to valid
ranges (non-negative in this case) if they are specified with `calc()`.
The length-related changes in this commit combined with the ones from
the previous commit fix the primary layout issue on https://lwn.net
(yes, not the first place I would have expected problems either).
...selector. Grammar per spec: `::slotted( <compound-selector> )`, so
we should reject selector as invalid if first compound selector is
followed by something else.
This change makes layout more correct on https://www.rottentomatoes.com/
...instead of `auto` Lengths.
This also fixes interpolating between two `auto` `<bg-size>`s, which
fixes a lot of animation tests for both `background-size` and `mask`.
Implements `::slotted()` to enough extent we could pass the imported WPT
test and make substantial layout correctness improvement on
https://www.rottentomatoes.com/
If a node with `contenteditable=true/plaintextonly` is the child of an
editable node or an editing host, we should make it editable instead of
an editing host. This effectively merges nested editing hosts together,
which is how other browsers deal with this as well.
Gains us 5 WPT subtest passes in `editing`.
For every ref tests actual and expected screenshots are taken. These
screenshots are only needed while the individual test executes. However,
they are never freed during the run, leading to a continuous increase in
memory usage of the test runner while executing ref tests.
With the number of ref tests growing, this currently amounts to nearly 3
GB of uncompressed bitmap data being held in memory. Lets avoid that by
clearing the screenshot data at the end of each test. With this change
applied, the memory usage of test-web stays stable and below 100 MB for
the entire test run.
`font-size` can end up with a negative value - either due to `calc`
being resolved using the old method which doesn't clamp the value, or
interpolation - in this case we should clamp negative values to zero.
Gains us 36 new WPT passes and fixes crashes in the three imported
tests.
Interpolation can leave `padding-*` values as negative - this should be
handled by interpolation clamping it to the allowed range of values
but we don't yet do that. As a stop gap we can clamp this before setting
it in ComputedValues.
This fixes 3 crashes and gains us 11 passes in the imported WPT tests
Currently, ImageProvider::current_image_bitmap takes a Gfx::IntSize
argument which determines the size of the returned bitmap. The default
value of this argument is 0x0 which causes the function to return
nullptr. This behavior is evidently unintuitive enough that it has lead
to incorrect usage in multiple places. For example, the 2D canvas
drawImage method will never actually draw anything because it calls
current_image_bitmap with no arguments. And the naturalWidth and
naturalHeight of an image will always return 0 (even after the image has
loaded) for the same reason.
To correct this and hopefully avoid similar issues in the future,
ImageProvider::current_image_bitmap will be renamed to
current_image_bitmap_sized, and the default value for the size argument
will be removed. For consistency, a similar change will be made to
SVGImageElement::default_image_bitmap.
The existing current_image_bitmap function will no longer take a size
argument. Instead it will always return a bitmap of the image's
intrinsic size. This seems to be what most existing callers had already
assumed was the function's behavior.
From the SVG spec
The value of the ‘viewBox’ attribute is a list of four numbers <min-x>,
<min-y>, <width> and <height>, separated by whitespace and/or a comma...
Currently try_parse_view_box will fail to parse the attribute if the
values are separated by commas.
This change replaces try_parse_view_box with a more correct
implementation. It will reside in the AttributeParser.cpp. This new
implementation correctly handles comma-separated viewBox values, and is
also more robust against invalid inputs.
Additionally, it adds a new test case to ensure viewBox values with
various syntax are parsed correctly and invalid values are rejected.
What I thought was a spec issue was actually a combination of my own
misunderstanding and a bug in our IDL generator. With that bug fixed, I
can correct this to how it is in the spec.
